Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer widely used as a binder, thickener, and film-forming agent in adhesives, textiles, paper coatings, and pharmaceuticals. It is also employed in detergent formulations and as a protective colloid in emulsion polymerization. This PVA has a molecular weight range of 30,000–70,000 g/mol, CAS number 9002-89-5, and the molecular formula (C₂H₄O)ₙ. It is stored at ambient conditions and carries a signal word of *Warning*. Molekula supplies Polyvinyl alcohol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
